What is the biggest transmission misconception?
That when you shift gears, you are physically engaging the teeth of the transmission. As seen in the picture above, the teeth of your transmission are always engaged, meshed, and moving. When you shift gears, what you are doing for both dog and synchro engagement is engaging the sliding mechanism inside the gears to apply power to the selected gear. When this occurs, a load is generated in that gear and forward motion occurs.
